For what it's worth, I went through the TVTropes Touhou page and sub pages just a few minutes ago. Currently waiting for the Characters page to be checked back in, which'll be in two minutes. Couldn't find a single Wikia link as of the moment, so props to you. Might have to check back every now and again for a while, in case some less knowledgeable but well meaning (Or maybe even less well intentioned) troper posts links to Wikia.
In any case, looks like the scouring's taken a good hold. Hate to see something like this have to happen, but really, some companies do that. If there's anything else I can do to help, say the word.
Edit: Character page is clean. I'm a bit too lazy to go through every single trope looking for links to clean up though. :colonveeplusalpha:
